HEELl-BURNISHING MACHiNE.

SPECIFICATION forming pari'. of Letters Patent No. 376,066l dated January 10, 1888.

Application filed April 16, i887.

To all whom 0' may concern: y

Be it known that I, JAMES H. BUSELL, of Boston, in the county of Sui'olk and State of Massachusetts, have invented certain new and useful Improvements in Heel-Burnishing Ma? in a novel method of burnishing the edges of boot or shoe heels as follows, viz: Burnishing the heel-edge in sections of its height in succession--as, the central portion first, then the portion next to the tread-Surface, and then the portion next to the heel-seat-and theburnishing of onesection overlapping the burnishing of atleast oneof the other sections.

It furtherconsists in the method of burnish- Aing the edges of boot or shoe heels, which plane of movement ofsaid tool, and, finally, api plying the heel-seat portion of the heel to the action ot' a separate moving burnishing and beading tool, as will be more fully described.

It further consists in a machine having certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description ofthe drawings and tothe claims, to be hereinafter given. y

Figure 1 of the drawings is a side elevation of a machine illustratingmyinvention. 2 is an elevation of the same, viewed from a direction at right angles to. Fig. l. Fig. 8 is a side elevation of the head ot' themachine, drawn to an enlarged scale. Fig. 4 is a plan of said head. Fig. 5 is a central vertical section through the bearings of the reciprocating tool-carrier and portions of said carrier, the remainder of said carrier being shown in ele vationwith the tool removed. Fig. 6 is a partial section on line x x on Fig. 5. Fig.'7 is a horizontal section on line y y onFig. 5, with Fig. Y

to an enlarged scale, with the heel to be bnr.-

nished represented in dotted lines in rposition for burnishing the edge of the top lift. Fig. 12 is a similar view with the heel represented in' position for burnishing its middle portion.

In the drawings, A is a column supported I by the legs AA,and provided in its base portion with bearings kai a, in which is` mounted the driving-shaft B, having mounted. thereon the tight and loose pulleys C and C and the larger pulley, C2, all as shown in Figs. l and 2.

To the upper end of the column A is rmly secured the frame D, the uppelaportion of which is forked and has formed therein the bearings D and D2, in which is vmounted the shaft E, having secured thereon the pulleysF f and F and the hand-Wheel G. rlhe bearings D and Dlare lined with composition bushings tixed therein, the bushing Dof the bearing D projecting beyond the outer end of said bearings and having adjustably secured thereon by the set-screw a the hub H, formed in one piece with the two cylinders H and H2, one above and the other below said hub, said cylinders serving as bearings for the verticallyreciprocating tool-carrier I, as shown in Fig. 5.

The cylinders H and H2 are lined with composition bushings Vb and b, and their outer ends are closed by means of the screw-caps H3 and H3, thus forming an air-chamber at each end of the tool-carrying piston l, the air in which serves as a cushion for said piston as itA appreaches the extreme of its stroke in one direction and as a spring to assist in moving it in the other direction.

The shaftE has set in its front end the crankpin c, upon which is mounted the rectangular block d, which in turn is fitted to a rectangular transverse slot, ci', cut in the back side'of IOO the tool-carrier Iin such a manner-'that when the shaft E and the crank-pin c are revolved Vsaid. block d will be moved in said'slottral'ri'sverselyof the tool-carrier while the latter isbeing moved vertically, or in the direction of said tool moving vertically horizontally, or at any desired angle, but in a right line.

The tool J is provided with the shank e, which is fitted to a socket, e', formed in the tool-carrier I, and is secured therein by the set-screw e2, and the workingfaee of said tool has formed thereon a series of horizontal beads, e, which serve as so many burnishingsurfaces, which act successively upon theheeledge presented thereto at each upward and downward stroke of the tool.

The guard J'l is secured to the tool J by serewsf, (shown in dotted lines in Figs. 4 and 7,)and is provided with the beading-shoulder g, extending from top to bottom thereof, as shown. The tread-guard J2 is located upon the tool J at some distance back of the extreme front part of the rounded portion of the tool J', so that in burnishing the central portion of the height of the heel the heel may be moved transversely of the tool J while it is being reeiprocated vertically without danger ofinjury to the top-lift edge by its coming in contact with the tread-gnard, as shown in Fig. 12.

K is a bifureated bracket bolted to the side of the frame D in bearings Kand Kl, on which bracket the shaft L is mounted, upon one end of which is secured the pulley L and upon the other end the heel-seatburnishing tool M, provided with frusto-conical beaded surface l1, the surface h for forming a bead on the heelseat, and the rand-guard It, all as shown in Fig. 4. A rotary motion is imparted to the shaft L and the burnishing-tool M from the shaft E through the medium of the belt N, as shown.

O is ajack-rod connected at its lower end by a ball-and-socketjoint to the stand P, secured to the base of the column A, and is bent, preferably, to the form shown in Fig. l, and has its upper end slotted or forked to receive the lever O', which is pivoted thereto at z', and provided at one side of said pivot with the pin j, to enter the hole in the last for the purpose the several burnishingsurfaees by taking the toe ofthe shoe in his right hand and the handle 'la in his left hand. The bent rod R is mounted in a bearing in a split box, in which it is clamped by a binding-screw, as shown in Figs. 2 and 10, so that it may be adjusted about the center of said bearing for the purpose of changing the line of draft ofthe spring Ql to adapt it to differently-shaped bnrnishingtools.

The cylinder H is made in two parts, SC- cured together by the bolts a a, for the purpose ot' enabling the toolfearrier to be placed in position in its bearings, the bushing in the cylinder H being inserted therein after the toolcarrier is placed in position in said cylinders.

The operation of burnishing a boot or shoe heel is as follows: Power being applied to the shaft B to revolve it by means ot' a belt (not shown) leading from the tight pulley C on said shaft to any suitable counter-shaft or main shaft, the operator inserts the pin 7' in the hole in the last upon which is the boot or shoe the heel of which is to be burnished, and taking the toe of the shoe in his right hand and the handle It of the lever O in his left hand, he first presents the edge of the heel tothe action 0f the beaded surface of the reciprocating tool J', as shown in Fig. l0, to burnish the central portion of the heeledge, moving the jackrod about its ball andsocket joint and the shoe about the pinj and the lever O about its Vfulcrum-pin, so as to present all parts of the heel-edge between the top lift and a point near the heel seat successively to the action of said tool, so as to completely burnish the central andthe greater portion of the height of the heel without attempting to finish the heel-seat or toplift portion ofthe heel. To accomplish this in the best manner, or so as to produce the best results, the operator imparts to the shoe-heel a lateral or sidewise motion, or a motion at right angles, or nearly so, to the motion of the burnishing-tool, saidlateral motion being variable at the pleasure or will of the operator, sometimes extending to the greater part of the height of the licei and at others to only a small fraction of such height. This he is enabled to do very efectually by virtue ofthe reaction of the spring Q, which must be so arranged and connected as to draw the heel hard against the burnishing-tool at whatever angle the heel may be presented to said tool. This will be best understood by reference to Fig. 10 of the drawings, where it will be seen that the line of draft of the spring Q is such that the heel may be moved to the right or left of the position shown a sufficient distance to cover the greater part of the height of the heel without bringing the line of draft so far outside of the burnishing-tool as to pull the heel away therefrom or injure the heel. He then presents the edge of the top lift to the action of the portion of the tool J next to the guard J2, with the tread-surface of the heel pressed fair against the tread-guard J2, manip- TOO IlO

Y guard and moving the heel laterally or across the line of movement of the tool and then iinishing the top lift upon another portion of the same tool and then the heel-seat'upon a separate burnishing-tool without removing the shoe from thejack, I am enabled to produce a tine linish upon all parts ofthe heel-edge without jamming thetop lift out of shape or cracking or injuring the finish on any part of the heel after it has once been produced.

The burnishing of the last two'operations overlaps the burnishing ot the rst operation sufficiently to insure a perfectfinish ofall parts of the heel. It is quite immaterial which of the last two operations takes precedence in point of time; but in order to'insure the best work the central portion of the heel must loe burnished lirst, and the two'extremes may then be finished in succession, either part being done first, as the operator may prefer; but, as a matter of convenience, I prefer to iinish the top-lift edge next after the middle portion and the heel-scat last. The end of the shaft E has three holes tapped therein at different distances from its center, in either' of which the crank-pin c may be 4screwedif it is desired to vary the stroke of the reciprocating tool-carrier. By turning the toolicarrier into a horizontal position, as indicated in dotted lines in Fig. 4, andinserting therein a tool adapted for the purpose, the machine may be used for burnishing the lreadfsurface ofthe shank portion of the sole.

Vhat I claim as new, and desire to secure by Letters Patent of the United States, is
